-IIERMANN JULIUS RICHTER, OF DRESDEN, GERMANY, ASSIGNOR TO MORITZ IVACKERNAGEL.

WA G O N SPECIFICATION forming part of Letters Patent No. 461,085, dated October 13, 1891.

Application tiled June 29, 1891. Serial NoA 397,762. tNo model.) Patented in Germany March 18. 1888, No. 45,319.

To all whom it may concern:

Be it k nown that I, HERMANN J ULIUs RICH- TER, a subject of the Emperor of Germany, residing at Dresden, Saxony, Germany, have invented certain new and useful Improvements in Vagons, (for which I have obtained a patent in Germany, No. 45,31), bearingdateilIarch 18, 1888,) of which the following is a specification, suliicient to enable others skilled in the Io art to which the invention appertains to make and use the same.

My improvements relate to the means employed for opening and closing the bottom of the wagon; and they consist in the special I5 construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure lis a sectional elevation of a wagon-body provided with my improvements; Fig. 2, a diazo gram matic plan of portions thereof; Fig. 3, a central longitudinal elevation within the frame of the wagon; Fig. 4, a plan of the front end of the draw-rod and connections.

Mounted upon the fram e-work of the wagon, at its front end, is the brake mechanism b, which is operated by the crank a. This brake mechanism forms no part of my invention.

Immediately behind the brake mechanism 3o b is mounted the vertical shaft c, at the lower end of which is the pinion f, which engages with the' rack-sliding bar g. The shaft c is also provided with a ratchet-wheel e, which engages with the pawl d, so that the opera-tor may control the opening or closing of the bottom of the wagon. The sliding bar g nearly extends the full length of the wagon and is mounted upon bearings h 7L 7L, which are connected to the side I-beamsm vm' and 4o constitute the frame-work of the wagon.

Mounted on the sliding bar g are eyes or hinges-t' c" rf, to which are connected the ends of the links 7; k 7e, the other ends of said links being connected, as at n, to the inclined bottom sections l I of the wagon. The inclined bottom` is made in two sections l Z and hung on longitudinal hinges p j), which are attached to the rib or rail '71, extending the whole length of the wagon-body, so that when the sliding rod g is moved forward the sections will assume the position shown in dotted lilies in Fig. l. A hood or cover o is provided, so as to protect the hinges p p from injury or from contact with dirt and other foreign substances.

As will be seen by reference to Fig. 2 ot' the drawings, when the sliding bar g is moved forward the links k 7;/ k, connected to the bottom Z draw them toward the center, as shown in dotted lines in Fig. l, practically leaving a clear space for the discharge of the cargo, &c.

To close the bottom of the wagon, the operator reverses or retracts thetbar g by means of the crank a and shaft c. Thus it will be seen that very little energy or power is required to open or close the bottom.

That I claim as my invention, and desire to secure by Let-ters Patent, is-

l. In a wagon substantially such as described, the combination Vof the hinged central bottom sections ZZ', the links 7i: k 7s", sliding rack g, pinion f, shaft c, and a crank n, the whole arranged and operating substantially in the manner and for the purpose described. 75

2. In a wagon substantially such as described, the combination ot' the hinged central bottom sections Z If, the links k k c, sliding rack g, pinion f, shaft c, ratchet-wheel e, pawl d, and the actuatingfcraul; a., the whole 8o arranged and operating substantially in the manner and for the purpose described.
